Another “rebuilt” transmission came into our shop WITH LESS THAN 10 MILES after a customer paid $1,500 elsewhere. Once we tore it down, we found it wasn’t fully disassembled, wasn’t properly cleaned, had incorrect parts installed, and was built with cheap components.

One of the biggest issues was a cracked forward drum where the shaft presses in. This caused the 3-4 clutch to burn up almost immediately, something the previous builder simply missed during the rebuild.

At 3MT Automotive, we believe in doing it right the first time. A quality rebuild costs more because quality parts and quality workmanship aren’t cheap, but neither is paying twice.

Invest in a rebuild that’s done right the first time, and save yourself the cost and frustration of having to do it all over again.

We made another trip to Alabama this weekend to pick up a customer’s car. (as well as some tune jobs) We’re incredibly grateful that so many of our jobs have us traveling all over. it definitely keeps life interesting! We also purchased a new car trailer so we can haul more vehicles and better serve our customers. Thank y’all for trusting 3MT Automotive! 💪

We know it’s tempting to bring your own parts or come in with what you think the issue is, and we completely understand!

Over time, we’ve learned the best way to take care of our customers is by doing our own diagnostics and using quality parts we trust.

It helps us avoid misdiagnoses, saves you time and money, and lets us stand behind every repair we do.

•Every vehicle gets our diagnoses no matter what
•Every vehicle gets parts from us no matter what

Thank you for trusting us with your vehicle 🤍
